GOLIATH DIFFUSERS - SPECIAL WALNUT

Frequency Coefficient Range: 600Hz - 4000Hz  
Weight: 50lbs
Dimensions: 2ft x 2ft x 8in
(Actual - 24.5in x 24.5in x 8in)

QUALITY FABRICATION:

Each diffuser is hand built by our team in North Carolina. We build every diffuser with care, love and attention to every last detail.

Each well (block) is sized & placed methodically, based off of a  primitive root equation for acoustic diffusion - to optimize effectiveness of the panel.  

These colossal skyline diffusion panels are fabricated using Western Red Cedar - Commonly used for acoustic instrument & guitar making. This results in a uniquely beautiful panel with appreciable visual characteristics and distinguished sonic attributes. Every single diffuser well (block) is stained by hand with a BEAUTIFUL Special Walnut wood stain to create a stunning finish and a truly unique panel.

Next Generation's exclusive Goliath Diffusers are designed to be visually beautiful, structurally durable and have the unique objective of scattering (diffusing) low & mid range frequency sounds equally in all directions. 

These diffusers are mathematically designed to diffuse and scatter mid-range / treble frequencies equally in all directions. The acoustic diffusion wells are calculated using a primitive root equation for diffusion. 

APPLICATIONS:

Goliath Diffusers will make a significant improvement acoustically & visually to studio rooms, live music rooms, theater spaces, mastering rooms, restaurants, venue stages, etc.

Goliath diffusers will help in taming muddy mid-range and low end frequencies within your room. They will allow sound to move freely - but will break up & evenly disperse sound reflections throughout the room. This can significantly improve acoustical properties in your space. This is due to the occurrence of direct reflections (sound bouncing back in forth from a wall to the opposite wall over and over again) being what causes decreased sonic intelligibility when it comes to reverberating frequencies inside of a room. 

Goliath Diffusers also help with correcting phase issues caused by the shape of your room and how audio is responding within it. Direct reflections caused by square/rectangular shaped rooms can create "peaks and nulls" in distinctive frequencies at various locations within a room.

These nulls develop when the amplitude of different frequencies significantly decrease in specific areas within the room. This occurs when the phasing of a reverberating audio wave meets an opposing wave formation at the same frequency causing phase cancelation. This means that the audio in your room is not being accurately represented and will have different perceived levels at different locations in the room. Our Goliath diffusers will aid in fixing this issue - especially in mid-range & treble frequencies. 

Peaks and Nulls cause audio within a room to not be accurately and evenly represented everywhere throughout the room. Having different levels of perceived frequencies at certain locations is extremely problematic in any critical listening, recording or mixing environment. Diffusers will aid in reducing/correcting peaks and nulls within your room. Especially when placed or installed at critical reflection points within the room.

 

Installation: 

These panels are heavier than standard acoustic panels and require adequate mounting hardware. Therefore each Sonic Diffuser panel comes with FREE custom mounting cleats. 

A "panel cleat" will be pre mounted onto the back of each panel. A corresponding "wall cleat" will also be included inside of the box with your order. Simply hang the provided "wall cleat" wherever you desire the panel to be placed on the wall.

Secure the wall cleat to a stud when/where possible. Wall anchors will substitute where necessary. Our custom panel cleats are made by hand in our shop & are cut to the exact specs of your Sonic Diffuser panel's framing. Our custom made Panel Cleating is the best method to utilize when hanging heavy acoustic / diffusion panels. Utilizing this method will save you A LOT time when installing your Sonic Diffuser and will insure they're mounted properly & secure.

Solid phone holder
This tesla magsafe phone holder was easy to install and works well, its compatible with any tesla and the magsafe magnetic ring is very strong and secure to my phone, and im pretty happy with that, it also is pretty adjustable so I can angle it so I can see it better, and overall is a great addition to any tesla. I do wish that the part connecting to the back of the screen to mount it was removable, because the only way to mount it is with the included adhesive and I didn't like that so much The build quality feels great and is well made. Overall though if you dont mind the adhesive mount its a great magsafe phone holder for teslas

Almost perfect
Style: Screen+Charger
Solid mount. I’ve tried other ones but they don’t sit as nicely as this one. It also has a lot of adjustments to allow for using it any way you need it to so it is very versatile. The magnet strength is really good and holds my phone really well. Sometimes it feels too strong which I guess is a good thing. The charging works well but I wish the cable was a little longer

Almost Perfect But With Workaround it Rocks
Style: Dash+Screen+Qi2 Charger, Style: Dash+Screen+Qi2 Charger
This works almost perfectly in my Tesla, with one small tweak for hot summer conditions. It holds my phone very well overall—I position it slightly off-center at about the 10 o’clock position. However, with a larger phone like the Galaxy S25 Ultra, the combination of weight and summer heat can cause the mount to slowly rotate as the suction cup loses some grip. I found a simple fix that works extremely well: applying a small amount of rosin (the same kind used for violin bows) to the friction point where the rotating arm meets the suction base. That added grip completely solved the issue. Now the mount stays exactly where I position it, even in the heat. Solid product, and with that minor adjustment, it performs exactly how I need it to.
